TIRE CONSTRUCTION.

SPECIFIGATIONbforming part of Letters Patent lilo. 696,391, dated March 25, 1902.

Application filed September 23, 1901. Serial No. 76,220. (No model.)

for removably securing the same to the wheel,-

the object of the invention being to provide strong and simple devices for securing a tire to the rim of a wheel without gripping the body of the tire itself, whereby its elastic movements laterally would be restricted; and a further object of the invention lies in the provision of means whereby the tire may be also secured against circumferential and lateral movement and yet be readily removable;

and the invention consists in the construction described in the following specification and summarized in the claims forming a part thereof.

In the drawings forming part of this specification, Figure 1 isa side elevation of a wheel and tire constructed according to my invention, parts of the tire and wheel being in section. Fig. 2 is an enlarged transverse sectional View through the tire and folly. Fig. 3 is a perspective view of a part of the rim of a wheel.

Referring noW'to the drawings, a represents the telly of a wheel; Z), a metal rim which may be secured to the telly in the usual manner by being shrunk thereon and being secured by bolts 0. As shown in Fig. 2, this rim preferably projects slightly beyond each side of the felly and has provided therein at 0 proper intervals, as shown in Fig. 3, marginal recesses d, which are oppositely located in the edges of the rim. These recesses are located around the rim, where it is desired to place the bolts whereby the tire is secured to 5 the rim. In the drawings these bolts are indicated by c, and extending transversely across the rim from one of these recesses to another there is a shallow groove f, in which the bolt-elies when in operative position. The

object of this groove f and the engagement 5o therewith of the bolt 0 is to prevent the circum ferential movement of the tire on the rim, or creeping, as it is. termed, and while the devices employed for securing the tire to the rim are deemed sufficient to prevent this creeping action the non-creeping of the tire is doubly assured by the engagementof the bolt 6 with these shallow grooves f, as described, and with a similar groove in the base ;of the tire.

The tire shown in the drawings and indicated by g illustrates a double-tube construction having a fiat base 7L,preferably of some- What less width than the rim 1), on which it is seated. This base h extends laterally of the tire beyond the point of its attachment to the latter, whereby an outwardly-extending flange is provided at each edge of the base, whose upper surfaces are Iupwardly inclined from the edges of the base, all as clearly shown in Fig. 2.

To secure the tire to the rim of the wheel,

a separate ring 2' is provided for each flange, the inner surface of which ring is beveled to fit the upwardly-inclined surface of the flanges of the base h. These rings 2' are fitted, respectively, over each of the flanged portions of the base h, and the bolts 6, fitting in suitable grooves in the base 71. of the tire and in the grooves f of the'rim, engage these rings i, the head of the bolt bearing against one and the not on the opposite end of the bolt bearing against the other, a suitable washer preferably being inserted between the nut and the edge of the ring. When the nut on this bolt is screwed up, the nut and washer on the one side and the head of the bolt on the other are adapted to enter the recesses (Z in the edge of the rim, to the end that still another means other than the groovesf may be provided for locking the tire to the rim against circumferential movement and to the end that the nut on the bolt in being screwed up may not bring up against the edge ofthe rim, whereby its further adjustment will be prevented.

The tire shown is divided longitudinally along itsbase line, to the end that an inner tubej may be inserted therein; but the particular form of tire employed is immaterial, for it may be of the type-shown, or it may be a single-tube tire, or it may be a solid rubber tire provided with the flanged base h. Either description of these tires'would be provided with the same rings 1' and bolts 8 for securing them to the rim. As the nuts on the bolts c are set up it is seen that the two rings '2; will be drawn together, thus gripping the base of the tire transversely and at the same time forcing the inner beveled surfaces of the rings against the similarly-beveled upper surfaces of the flanges of the base, thereby at the same time binding the base on the rim. The inner edges of these rings 2' are rounded, as shown, and the upper surfaces of the rings constitute two bearing-surfaces, againstwhich the tire may seat itself forsupport when it is compressed by a load upon it.

From the above description it is seen that practically four-fifths of the circumferential wall of the tire is free to take any position imposed upon it by the condition of the load it bears, and yet by means of the devices described the tire may be so firmly gripped as to readily withstand any lateral or circumferential strains put upon it, and yet be readily removable.

Of course it Will be understood that the invention may be applied to any form of a wheel and felly.

While it would be possible to apply a tire to the felly of a wheel not provided with a rim 1) by locating the grooves f and the recesses d of said rim in the felly, such a construction would not be desirable, though it would clearly fall within the scope of this invention.

It will be observed that by means of the herein-described construction the base of the tire is clamped to the wheel along the entire circumference thereof and the tire locked to the Wheel by positively interlocking means, whereby lateral or circumferential movement of the tire relative to the rim is prevented, and the tire is not dependent upon mere frictional contact with the rim for holding it in place on the latter.

Having thus described my invention, what I claim,and desire to secure by Letters Patent of the United States, is-

1. In combination with the felly of a wheel,

a tire, a fiat base thereon adapted to fit the periphery of the felly, a downwardly-beveled flange on each side of the base, a loose ring located on each flange, and devices for moving said rings one toward the other against said beveled surface, and means of engagement between said devices and the felly, substantially as described.

2. In combination with the felly of a wheel, a tire, a flat base thereon adapted to fit the periphery of the felly, a flange on each side of the base, the upper surface of which is downwardly inclined toward the edge of the base, a loose ring located on each flange and having a beveled under surface, and devices for moving said rings one toward the other, and means of engagement between said devices and the felly, substantially as described.

. of a flat metal rim secured thereon, a tire, a

base on the latter, and means for securing said base to said tire against lateral and circumferential movements consisting of a ring located over each edge of said base, and bolts adapted to engage said rings whereby they may be drawn one toward the other, and means for interlocking said bolts and said rim substantially as described.

5. The combination with a wheel, of a flat metal rim thereon, a tire having an outwardlyflaring flanged base fitting over said rim,rings having a greater diameter than .said rim on either side of said base fitting over the outwardly-flaring portions thereof, and means for drawing said rings together-whereby said base portions may be radially compressed against the rim.

6. In combination with the felly of a wheel, a tire, a flat base thereon adapted to fit the periphery of the felly, a flange on each side of the base, the upper surface of which is downwardly inclined toward the edge of the base, a loose ring located on each flange and devices for moving'said rings one toward the other, and means of engagement between said devices and the felly, substantially as described.

7. The combination with a wheel, of a flat metal rim, a tire having an outwardly-flaring flanged base fitting over said rim, rings on either side of said base having a greater diameter than said rim and adapted to fit over said base portion of the tire, and means for drawing said rings together whereby said base and means for forcing said ring over the edge of said base whereby the latter may be clamped between said ring and said rim.
